Clinical Report: Cardiac Resynchronization Therapy Defibrillator Implantation with Left Bundle Branch Pacing in a Patient with Mirror-Image Dextrocardia

Overview

This report details a case of cardiac resynchronization therapy defibrillator implantation using left bundle branch pacing in a 73-year-old male with mirror-image dextrocardia and advanced heart failure.

Background

Mirror-image dextrocardia is a rare congenital condition with an incidence of approximately 0.01%. The complete reversal of cardiac anatomy complicates standard cardiovascular interventions, particularly in patients requiring cardiac pacing. Cardiac resynchronization therapy (CRT) is recommended for heart failure patients with complete left bundle branch block, but its application in mirror-image dextrocardia has been minimally explored.

Data Highlights

No numerical data or trial data provided in the source material.

Key Findings

• Successful implantation of an LBBP-based CRT-D in a patient with mirror-image dextrocardia.
• Preoperative mirror-image adaptation of ECG and DSA systems was crucial for the procedure.
• Advanced heart failure and CLBBB were present in the patient.
• Accurate capture of the left bundle branch was achieved intraoperatively.

Clinical Implications

This case underscores the importance of tailored approaches in CRT for patients with unique anatomical challenges. The successful use of LBBP in this context may inform future practices for similar cases.

Conclusion

The implantation of an LBBP-based CRT-D in a patient with mirror-image dextrocardia demonstrates the feasibility of this approach despite significant anatomical challenges. This case contributes valuable knowledge to the field of cardiac pacing in complex congenital conditions.
